White-Rodgers 90-248 Contactor
The White-Rodgers 90-248 is a high-performance 2-pole definite purpose contactor engineered for demanding central air conditioning and heating systems. As a Type 122 contactor, this component is designed for reliable inductive load switching, featuring a 120V coil and robust 40-amp contacts. The low-VA coil design, with a 224-ohm DC resistance and a nominal power consumption of only 6 VA, ensures cooler operation and helps prevent premature coil burnout by minimizing heat generation during extended duty cycles. With a maximum inrush of 32 VA, it handles initial startup loads effectively without compromising internal electromechanical components.
For service technicians, the White-Rodgers 90-248 offers a versatile footprint with a universal style mounting bracket that aligns with standard OEM hole patterns for rapid field replacement. It features double-break contacts for a positive make-and-break sequence, reducing arcing and extending the life of the DPST (Double Pole Single Throw) configuration. Termination is streamlined via pressure connectors and dual 1/4-inch quick connects, making it a reliable drop-in for HVAC contactor replacements in 120VAC control circuits. This unit is rated for up to 600V and functions across a wide temperature range from -40°F to 150°F, ensuring performance in unconditioned mechanical spaces.
Key Benefits of the White-Rodgers 90-248- High Current Capacity: Rated for 40A inductive loads and up to 50A resistive loads, suitable for high-tonnage condensing units.
- Efficient Coil Dynamics: The 120 VAC coil runs at 50 mA, reducing energy draw and thermal stress on the control transformer.
- Universal Compatibility: Fits existing mounting holes for a variety of brands, serving as a direct White-Rodgers 90-248 cross reference for many OEM parts.
- Rugged Construction: Features high-quality thermosetting resin contact blocks and a Class B coil insulation rating (130°C).
- Can the White-Rodgers 90-248 replace a 30-amp contactor? Yes, this 40-amp contactor can safely replace lower amperage 2-pole units with a 120V coil, providing additional headroom for inductive loads.
- What are the primary terminal types on this 2-pole contactor? It includes both screw terminals/pressure connectors and double 1/4" quick-connect tabs for flexible wiring.
- Is this suitable for 24V control systems? No, the 90-248 model requires a 120V control signal to pull in the contacts; for 24VAC systems, the 90-244 is the appropriate equivalent.
